Reversible Structural Transition of Two-Dimensional Copper Selenide on Cu(111)
Yuan Zhuang, Yande Que, Chaoqiang Xu +2
Structural engineering opens a door to manipulating the structures and thus tuning the properties of two-dimensional materials. Here, we report a reversible structural transition i…
On-Surface Synthesis of Graphene Nanoribbons on Two-Dimensional Rare Earth-Gold Intermetallic Compounds
Yande Que, Bin Liu, Yuan Zhuang +3
Here, we demonstrate two reliable routes for the fabrication of armchair-edge graphene nanoribbons (GNRs) on TbAu2/Au(111), belonging to a class of two-dimensional ferromagnetic ra…
Two-Dimensional Rare Earth -- Gold Intermetallic Compounds on Au(111) by Surface Alloying
Yande Que, Yuan Zhuang, Ziyuan Liu +5
Surface alloying is a straightforward route to control and modify the structure and electronic properties of surfaces. Here, We present a systematical study on the structural and e…
Half-filled intermediate bands Si material formed by energetically metastable interstitial sulfur atom
Ke-Fan Wang, Mingguo Liu, Yaping Ma +3
Hyperdoped metastable sulfur atoms endow crystalline silicon with a strong sub-bandgap light absorption. In order to explore such metastable states, we develop a new high-throughpu…
Induced effects by the substitution of Zn in Cu2ZnSnX4 (X = S and Se)
Guohua Zhong, Kinfai Tse, Yiou Zhang +7
Based on the density functional theory with hybrid functional approach, we have studied the structural and thermodynamic stabilities of Cu2MSnX4 (M = Zn, Mg, and Ca; X = S and Se)…
A novel strategy to control defects and secondary phases of CZTS by surfactant Potassium
Yiou Zhang, Kinfai Tse, Xudong Xiao +1
Cu2ZnSnS4 (CZTS) is a promising photovoltaic absorber material with earth abundant and nontoxic elements. However, the detrimental native defects and secondary phases of CSTS will…
Nearly Free Electron States in Graphane Nanoribbon Superlattice
Qiaohong Liu, Zhenyu Li, Jinlong Yang
Nearly free electron (NFE) state has been widely studied in low dimensional systems. Based on first-principles calculations, we identify two types of NFE states in graphane nanorib…
Nearly Free Electron States in Graphene Nanoribbon Superlattices
Shuanglin Hu, Zhenyu Li, Qiaohong Liu +3
Nearly free electron (NFE) state is an important kind of unoccupied state in low dimensional systems. Although it is intensively studied, a clear picture on its physical origin and…
